HORSE-COLLAR PAD.

SlI-ECIFZCATION forming part of Letters Patent No. 335,382, datedFebruary 2, 1886.

Application filed August 4, 1885. Serial No. 173,558.

To all whom, it may concern.-

Be it known that 1, WILLIAM H. Osman, a citizen of the United States,residing at St.

. Louis, in the State of Missouri, have invented ject by the mechanismillustrated in the accompanying drawings, in which Figure 1 is aperspective view of my improved hook. Fig. 2 is a central longitudinalsection of same. Fig. 3 is an elevation of book, open and secured to acollar-pad. Fig. 4 is an elevation showing hook as secured to acollar-pad, and the whole attached to a horse collar.

Similar letters refer to similar parts throughout the several views.

A represents the shank or fixed part of my improved hook, having ears B.

0 represents the curved clamping-arm of the hook, provided with ears D.

The parts A and O are hinged or pivot-ally united by passing a pin, E,through the ears B and D. The pin E is encircled by thecompressingspring F, having the ends G and H H, which bear upon theparts 0 and A, thus retaining the hook in its normal position, as shownin Fig. 1.

I represents the detent or stop in the joint of my improved hook. Thehook is secured to the collar-pad L in this instance by the rivets Kpassing through the pad Land holes J J in the shank A, and riveting thesame to gether, although any other suitable means for securing the hookto the collar-pad may be provided without departing from the spirit ofmy invention.

M represents a horse-collar. roll of same.

The parts A and O of this hook may be steel, brass, malleable cast orwrought iron, or any other suitable metal.

The object in making this hook jointed or in two parts, as shown, isthat where the part N is the front (Yo model.)

which encircles the front roll of the horse-collar is in one continuouspiece of metal, the constant strain from continued use at that part ofthe hook soon destroys and renders the hook useless. Especially is thistrue where these hooks or clasps are constructed of flat steel strips,for to a skilled metal-worker it is obvious that it is extremelydiflicult to attaili as exact a temper in thin steel strips as isrequired in hooks encircling the small roll of a horse-collar for thepurpose designed. Again, when finished in proper temper, the constantexpanding strain upon the clasp or hook when in use soon causes it torelax its grip upon the roll of a horse-collar and slip off the same,while by hard-tempering (which is often unavoidable) the hook becomes sobrittle that slight expansion breaks it.

The steel-wire hook, having a coil compression-spring, unless carefullyattached and re moved, has a tendency to cut or gouge the roll of acollar and partially destroy it.

I am aware that there are collar-pad hooks in two parts; but I do notknow of any such hook being jointed in the circle of the clasp for thepurpose of attaining the beneficial re sult referred to above. A slidingor extension hook or clasp is objectionable, as it is not posi tive inits action, the extension -strip being liable to slip back at any timeand detach the pad from the horse-collar.

It is to be understood that I am not to limit myself to any precise formor size of the spring F, or manner of applying it, so long as its officeis substantially the same in combination with a joint book, as shown inFig. 1. One hook is generally attached to each end of the collar-pad L.The whole is then attached to a horse-collar, M, by booking the claspover the front roll, N, as shown in Fig. 4.

It will be seen that my improved hook will admit of adjustment onvarious sizes of horse collar rolls. The parts A and 0 being actuated bythe spring F, a positive and constant grip upon the collar-roll isattained without straining the parts A and (3.

The attachment of hooks to horse-collar pads is not new. I do not claimsuch a device, broadly; but

XVhat I do claim is- 1. As an attachment to a horse-collar pad, ajointed metal hook consisting of a curved shank, A, adapted to besecured to a collarpad, and a clamping-arm, C, pivotally united by apin, E, and actuated by a spring, 'F, all substantially as and for thepurpose specified. 5 2. A jointed hook for horse-collar pads, having acurved shank, A, adapted to be secured to a collar-pad, and aclamping-arm, O,

in combination with a separate independent compression-spring adapted tocompress said IO jointed parts, substantially as and for the purposedescribed.

3. In a hook for horse-collar pads, the jointed part A, adapted to besecured to a collarpad and provided with ears B, and the clamp- 5ing-arm 0, having ears D, in combination with
